Are you a fan of the pucker? The Sultan of sour? Do you love that tight feeling you get at the back of your mouth when you chomp down on a lemon or find Warhead candies to be the absolute best thing in the world? Maybe you go for a subtler sour, like that found in lemon-flavored cookies and cakes, or the delightful bite of rhubarb. Maybe you just have a particularly sour attitude or know someone who does? If any of these are true for you, Sourest Day is going to be your new favorite holiday… Or not. Sourpuss.
